Case IH 10035 – Multi-System (INST, PERF, PTO, ENG): Multi-System Controller Error

Fault code 10035 is a multi-system code that means different things depending on which Control Module/ECU logs it. INST: Controller Memory Error - Loss of Valid Radar Configuration Information. PERF: Controller Memory Error - Loss of valid fuel table information. PTO: Controller Failure (ADC lock-up). ENG: Fuel Temperature Sensor - Signal Below Range Minimum.

• Case IH Magnum Series Tractors (MX series, 215, 275, 305, and TG series)

1. 1

   System Voltage Check: Test the battery voltage. It must be a steady 12–14 volts. Low voltage or a failing alternator (outputting below 14V) can cause memory loss or ADC lock-ups in the controllers.

2. 2

   Wiring & Ground Check: Verify that the affected controller has a clean, secure connection to the battery and is properly grounded. For the INST controller, check connector CN2 (specifically pin 2 for power and pin 4 for ground). For the PERF controller, check connector C062.

3. 3

   Software Version Check (PERF only): Check if the performance monitor software was recently updated (e.g., from version 1.0.0.0 to 1.1.0.0) without a new fuel table being loaded.

1. 1

   Verify power and ground

   If the code is INST 10035 (Radar Configuration Loss): Verify power and ground to the instrumentation controller.

2. 2

   Perform Radar Calibration

   Perform a Radar Calibration procedure exactly as outlined in the tractor's Operator's Manual.

3. 3

   Clear fault code

   Clear the fault code using the display or an approved diagnostic tool.

4. 4

   Restart tractor

   Shut down the tractor, wait for the modules to power down, and restart.

5. 5

   Replace Instrumentation Controller

   If the fault code returns immediately, the controller's internal memory is defective and the Instrumentation Controller must be replaced.

6. 6

   Connect EST

   If the code is PERF 10035 (Fuel Table Loss): Connect the CNH Electronic Service Tool (EST).

7. 7

   Load fuel table

   Navigate to the fuel update screen and load the new/correct fuel table into the performance monitor.

8. 8

   Clear code and restart

   Clear the fault code, shut down the tractor, and restart.

9. 9

   Replace Performance Monitor Controller

   If the code persists, replace the Performance Monitor Controller.

10. 10

    Hard reset

    If the code is PTO 10035 (Controller Lock-up): Shut down the tractor to attempt a hard reset of the controller.

11. 11

    Recalibrate PTO controller

    Restart and attempt to recalibrate the PTO controller.

12. 12

    Replace PTO controller

    If the code returns after calibration, the PTO controller is internally shorted/locked and must be replaced.
